Dead: Isabel Chavalo Gutierrez died while raping a 77-year-old woman
A registered sex offender died while raping an elderly woman at knifepoint in her home.
Isabel Chavelo Gutierrez, 53, from Tivoli, Texas, rode two miles from his home on his bike where he broke into his 77-year-old victim's house.
Authorities say that while he was raping her at knifepoint, he told her he wasn't feeling well and stopped having sex with her so he could rest.
Moments later he then went back to fondling her briefly before he rolled over and died.
